Too much positivity is just as bad as negativity

I’m glad some people have a positive attitude but too much positivity and not seeing that failure helps you learn or not letting people have their down time, makes things worse. That’s toxic positivity. Toxic positivity is just as bad as negativity. Let people have their moment and let them vent. Don’t dismiss them or discourage them from having feelings. I’ve been told to just think positive and being sad all the time isn’t going to help. I mean that is true but covering feelings doesn’t help. Just being honest.
Hey nothing wrong with being positive.
